12、9、12.66,01.74DIN16901:07.73修訂與1973年6月版本對比，本標(biāo)注修訂內(nèi)容如下：在表1中增加了模塑材料的數(shù)晝對表2進(jìn)行了重新排版：首次添加了“概念”章節(jié)。注釋本標(biāo)準(zhǔn)由FNK小組委員會(huì)501.1制定在精密工程使用公差時(shí)，本標(biāo)準(zhǔn)無法給出模塑材料與表2中公差等級(jí)的相互關(guān)系。因此在粘密工程應(yīng)用公差等級(jí)時(shí)，供應(yīng)商和客戶需確定公差等級(jí)是否可以與使用材料想匹配。對大量模塑件測量的實(shí)際尺寸偏差呈現(xiàn)出正態(tài)分布，因此町按DIN55302對于測量結(jié)果做統(tǒng)計(jì)學(xué)的評(píng)估。表2中的公差僅僅是生產(chǎn)公差，而不是全部公差。這是考慮到實(shí)踐過程中，后收縮和膨脹町能發(fā)生在任何情況卜發(fā)生，而沒何方法可以對其評(píng)估。
